The control of plant growth by thermopriming (A05)

Plants can be protected from an otherwise deleterious or even lethal heat stress (HS) by a prior moderate (priming) heat treatment. Notably, the capacity of a plant to withstand a damaging HS is maintained over a couple of days after the priming and reflects the presence of a thermomemory. The plant’s shoot apical meristem (SAM) is of crucial importance in this process. Project A5 will analyse the molecular mechanisms of thermopriming for the functional maintenance of the SAM in the model species Arabidopsis thaliana, with a particular focus on primary carbon metabolism genes and the effect of heat stress on the meristem maintenance genes CLV1 and CLV3.
